    What drives species to evolve? How can intricate structures such as the human eye, the spider's web or the wings of birds develop, seemingly by chance? Regarding evolution's most complex achievements as peaks on a metaphorical mountain, Climbing Mount Improbable reveals the ways in which the theory of natural selection can precisely explain the beautiful, bizarre and seemingly 'designed' complexity of living things.And through it all runs the thread of DNA, the molecule of life, responsible for its own destiny on an unending pilgrimage through time. Accompanied by evocative illustrations, Dawkins's eloquent descriptions of the living world's astonishing adaptations throw back the curtain on the mysteries of 'Mount Improbable'.An alternative cover edition for this ISBN can be found here.

    And few things taste more delicious than fruit picked straight from the tree or bush and eaten when perfectly ripe, perhaps still warm from the sun. This is fruit the way nature intended, not fruit that has been flown in from hundreds or thousands of miles away or stored in climate-controlled warehouses before being sealed in plastic for supermarket shelves. What could be fresher, tastier, more local, and more seasonal than fruit you've grown yourself, in your own garden or allotment, picked at just the moment when it's at its most perfect?This book shows just how easy it is to grow your own fruit. You don't need a huge garden or a dedicated orchard. It's possible to get a perfectly good harvest from plants grown in containers on balconies or patios and from even the smallest of town gardens. Pick the right varieties for the conditions you've got, invest in a bit of planning and preparation, follow the instructions contained in these pages, and you can be harvesting and eating your own strawberries, plums, pears, apricots, blackberries, redcurrants, melons, and figs.

    A total eclipse of the Sun will be visible from within a narrow corridor that traverses the United States. The path of the Moon's umbral shadow will begin in the northern Pacific and cross the USA from west to east from Oregon to South Carolina. The Moon's penumbral shadow will produce a partial eclipse visible from most of North America. In fact, the 2017 full eclipse is such an important sky event that sky watchers in Europe are already planning trips to view it. 2017 Guide to the Night Sky provides all of the information needed to view this exciting eclipse and track its path. The time zones and transit of the eclipse will be noted inside the book's jacket for quick and easy reference.The night sky makes for exciting viewing any time of the year, and 2017 Guide to the Night Sky is the ideal guide to help amateur astronomers find their way for the entire 12 months. With monthly charts and other diagrams set for a latitude of 40 degrees North, it shows how the visible stars change from month to month and includes the many sky events that occur throughout the year. It is highly practical for beginning sky gazers because the objects and events may be observed with the naked eye, or nothing more complicated than a pair of binoculars.The month-by-month guides include sky activity charts and moon calendars; meteors (with dates of showers, including hourly rate of radiants); the Planets; ecliptic charts; diagrams of interesting events; plus sky and constellation maps throughout.An appendix includes a full glossary; the Greek Alphabet; the constellation genitives, abbreviations and English names; a table of common asterisms; further information; recommended astronomy journals, societies, institutions and organizations; software, and internet sources.Especially useful for beginning sky watchers, this guide will be fully updated to 2017. Its small and light format makes it the ideal portable reference for backyard astronomers.

    Never before in history have children been so plugged in—and so out of touch with the natural world. In this groundbreaking new work, child advocacy expert Richard Louv directly links the lack of nature in the lives of today's wired generation—he calls it nature deficit—to some of the most disturbing childhood trends, such as rises in obesity, Attention Deficit Disorder (ADD), and depression. Some startling facts: By the 1990s the radius around the home where children were allowed to roam on their own had shrunk to a ninth of what it had been in 1970. Today, average eight-year-olds are better able to identify cartoon characters than native species, such as beetles and oak trees, in their own community. The rate at which doctors prescribe antidepressants to children has doubled in the last five years, and recent studies show that too much computer use spells trouble for the developing mind. Nature-deficit disorder is not a medical condition; it is a description of the human costs of alienation from nature. This alienation damages children and shapes adults, families, and communities. There are solutions, though, and they're right in our own backyards. Last child in the Woods is the first book to bring together cutting-edge research showing that direct exposure to nature is essential for healthy childhood development—physical, emotional, and spiritual. What's more, nature is a potent therapy for depression, obesity, and ADD. Environment-based education dramatically improves standardized test scores and grade point averages and develops skills in problem solving, critical thinking, and decision making. Even creativity is stimulated by childhood experiences in nature. Yet sending kids outside to play is increasingly difficult. Computers, television, and video games compete for their time, of course, but it's also our fears of traffic, strangers, even virus-carrying mosquitoes—fears the media exploit—that keep children indoors. Meanwhile, schools assign more and more homework, and there is less and less access to natural areas. Parents have the power to ensure that their daughter or son will not be the "last child in the woods," and this book is the first step toward that nature-child reunion.

    The pictorial models are useful in understanding relationships. The models also abound in descriptive detail.

    Amateur and expert alike can quickly and accurately identify almost any wildflower using Lawrence Newcomb's system, which is based on natural structural features that are easily visible even to the untrained eye. Every time you see an unknown plant, ask yourself the same five questions (related to the type of plant and the structure of its petals and leaves), and you will be directed to the page on which the plant can be found. Beautiful illustrations make confirmation easy.
